い場合にはサブコントローラー１７は不要である。FIG. 2 is a block diagram showing the configuration of the wireless repeater 6.
The first relay equipment includes an antenna 7 for the base station channel, a transmitter/receiver duplexer 8. Equipped with a multi-channel receiver 9 for main area A,
During standby, one of the idle channels of the base station wireless device 1 is being received. A transmitter 10 is provided in pair with the receiver 9,
A transmitter 10 is provided as a pair with the receiver 9, and when the receiver 9 switches the channel, the transmitter 10 is switched to the paired channel. 6 channel synthesizers for channel switching,
- Mi f 11 can switch to all of the base station channels. The channel synthesizer 11 is connected to a controller 12, and the controller 12 controls various operations necessary for communication, such as channel switching and turning on and off the transmitter 10. Receiver 9 is transmitter 1 of the channel dedicated to slave area B.
3, and the output signal of the receiver 9 is retransmitted to the terminal station 6 in the sub area B in a detection relay format. A transmitter 13 and a paired receiver 14 are provided, and the frequencies of the receiver 14 and the transmitter 13 are fixed to one of the channels dedicated to the slave area B. The transmitter 13 and receiver 14 are connected to a sub-area antenna 16 via a duplexer 16. A plurality of such repeaters are prepared, and the figure also shows a second repeater {circle around (2)}, and the same parts are shown with the same reference numerals and dashes. Each of these repeaters 1. A sub-controller 17 is provided to control the operation of the base station wireless device 1, and allows multiple repeaters to listen to different idle channels of the base station wireless device 1, or when there is only one idle channel, it is possible to use one repeater and connect other devices. 6 Perform actions such as stopping the page. Note that if there is only one repeater, the sub-controller 17 is not necessary.

transmission frequency. The number of repeaters to be prepared in the secondary area B is determined by the call loss rate and the call volume of the terminal stations 6 in the secondary area B. Furthermore, if the number of repeaters used here is two or more, there is an advantage that even if one of the repeaters breaks down, the call loss rate will only deteriorate.

ができる。In this relay method, the receiving frequency of the repeater is the same for both the channel to the king area and the channel for the slave area B, and the transmitting frequency is also the same band, and the transmitting and receiving frequencies of the repeater are separated. There is no need to worry about the transmitting output for page 7 slave area B going around to the receiver input. Therefore, it is possible to freely select the transmission output, and even if the relay station is installed outside the service area of terminal station 2 in main area A, sufficient line quality can be maintained by ensuring that the antenna is sufficiently high relative to the base station. The transmission power can be set freely for the slave area B.
